Title: Improvements in and relating to knitting machines
IPC: D04B9/18
Filed: 1930-06-04
Abstract: 351,714. Knitting-machines. HADDAN, R., 31, Bedford Street, Strand, London.-(Scott & Williams, Inc.; 366, Broadway, New York, U.S.A.) June 4, 1930, No. 17272. [Class 74 (ii).] Means are provided for engaging a withdrawn splicing yarn with the fabric formed on the needles which do not receive the splicing yarn. The invention is particularly applicable to machines for knitting spliced stockings having contiguous ribbed and plain portions. In rib machines the splicing yarn y, after being fed to the splicing needles, is caused to lie exteriorly to the loops r of the ribbed wales and interiorly of the loops a of the face wales, so that that portion of the yarn y exterding around the inside of the unspliced part, e.g. the stocking instep, is caught in front on the dial loops r<1>, r<2>, &c. The splicing yarn guide F<1> is actuated, as usual, by a lever 460 controlled by the pattern drum, but is provided with a cam 19 upon its under surface, so that when the lever 460 is engaged by a cam 295, rotating with the needle cylinder, the yarn guide F<1> is lifted to an intermediate position for positioning the yarn between the rib and face wale loops. The splicing yarn may be positioned for reception by, or with respect to, the needles by a member 26 pivotally mounted with the guide F<1>, and arranged between the guide and the position at which the needles receive the yarn. Additionally, and as applied to machines having two part dial needles, jacks 30 having bevelled ends 32 may be provided for depressing the splicing yarn beneath the level of the loop drawing instruments d<2> of the dial needles.

Title: Transfer devices for data recorded on storage devices or the like
IPC: G06F7/498
Filed: 1955-06-17
Abstract: 791,007. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 17, 1955 [June 18, 1954], No. 17535/.55. Class 4Q (1). The invention relates to an apparatus for transferring data from relay-operated storage units or digit emitters to electronic counters or the like in a computer. In Fig. 1, the contacts A1, A2, A4, A8 represent one of a plurality of storage units operating according to the code 1, 2, 4, 8, and F1-1 to F1-9, are outputs corresponding respectively to the digits 1 to 9. Each output F is provided with a control stage, Fig. 2, comprising a valve T having a first control grid which is controlled by a voltage applied from an output F, and a second control grid controlled by an impulse generated at the point in the cycle of the computer corresponding to the value considered. The cycle is divided into twentyfive intervals, Fig. 4, represented by impulses C, intervals 13 to 21 corresponding respectively to digits 9 to 1. If, for example, digit 9 is registered, contacts A1-b, A8-a, are changed over, and to transfer this value terminal A9 is energized to drive the grid of valve A 10 negative. Valve A 10 is cut off and the voltage increase on line 22 is transmitted via diode A11 and line F1-9 to the grid G1 of valve T, (curve E of Fig. 4, between points 1 and 10). The duration of the voltage increase depends upon the impedance of the reading circuits, and enables the counter reset operation to be carried out. At point 13, corresponding to digit 9, a positive impulse D is applied to grid 92 of valve T to render the valve T conductive, and an impulse is transmitted via valves I1 and 12 to a device controlling counter read-in. The sign of the value is recorded by contacts A15 of the storage unit, closure of contacts A15 causing a bias voltage to be applied when A10 is cut off, via diode A12, to one grid of a control valve, Fig. 3 (not shown), and at point 11, Fig. 4, which is reserved for sign reading, a second impulse is applied to the second grid of the valve to render it conductive, to produce an impulse representing the sign. Neon tubes for indicating may be connected to points N of the control stages. The application of the transfer device to an apparatus for setting up a digital input, e.g. for calculating tariffs, by means of plug-and-socket connections is described, Fig. 5 (not shown).

Filed: 1961-05-16
Abstract: 982,580. Winding tuft yarn spools; collecting and removing spools from machines; creels. JOHN CROSSLEY & SONS Ltd. May 14, 1962 [May 16, 1961, No.17803/61. Headings D1E,D1F, D1J and D1M. A method of spool setting comprises selecting from previously wound elemental bobbins a bobbin wound with a thread of a colour corresponding to a square in a line of the pattern and automatically assembling a plurality of so selected bobbins in the same colour sequence as that of the line of the pattern. The selection may be performed manually, mechanically, electrically or electronically e.g. by depressing the buttons of a keyboard, by a punched card, magnetic tape or a light-sensitive device. In Fig. 2 a manually operated keyboard causes a table 30 to rotate and drop bobbins in the required sequence into a trough 36 which passes them to a trough 37 where a shaft is caused to pass through them to form a tuft yarn spool. In Figs. 3 and 5 forty eight winding stations, each for a different colour, wind yarn on to bobbins which are doffed on to spindles 68-71 on a rotatable table. When a bobbin is selected it falls on to a conveyer 60 which transports it to a shoot 74 where it is dropped on to a spindle 75 to form a tuft yarn spool. When a spindle 68-71, of a station 1-48 is exhausted the table rotates to bring a full spindle over the dropping station and the winding machine winds more bobbins and doffs them on to the empty spindle. The bobbins may be of wood, metal, natural or synthetic resin or the bobbin may consist of the wound yarn itself. The conveyer is moved intermittently so that it is stationary when a bobbin falls on to it.
Patent GB-178224-A (GB)
Abstract: 178,224. Pehrson, A. P., and Lloyd, H. Jan. 20, 1921. Magneto-electric machines. -In an ignition magneto adapted to supply current for lighting purposes a switching device is provided which closes the circuit to an accumulator in the lighting circuit during and only during the whole time that the instantaneous voltage of the magneto exceeds a predetermined value. In the construction shown a bell-crank lever E weighted at one end e<1> and carrying at the other end a brush G is mounted to rotate with the armature. The brush G cooperates with a contact A connected by a terminal D to the accumulator circuit and mounted in an insulating disc C in the cap B. The brush G moves under the action of centrifugal force into contact with the contact A when the speed of the magneto reaches the value at which the electromotive force generated is slightly greater than that of the accumulator. As the speed of the magneto increases the brush G moves across the face of the contact A. The shape of the contact A is such that at all speeds of the magneto armature the brush G is in contact with it during the whole time that the electromotive force induced in the armature is above the predetermined value. Alternate half-cycles are used for battery charging and lighting, the other halfcycles being used for ignition. The contact surface on which the brush G bears when not in contact with the contact A mav be of the same material as the member A, this member being insulated from it.
